Photovoltaic Water Pumping System

Photovoltaic Water Pumping System

ABSTRACT

ADEQUATE quality and reliability of portable water supply is required not only for the human life but also by industries and agriculture. A variety of pumping techniques are available to meet the water demand. In term of mechanical pump (i.e. non-hand operated pumps) the most common type of the pump is either the ac pump (run by using main electricity) or the diesel pump. It is true that such pumps are technologically well understood, able to be transported at modest cost, relatively easy to install, etc. But the main problem associated with such units is their use in the remote areas where there is no electricity or diesel available for pumping water from bore holes. It is, therefore, in this context that to meet the growing world-wide water supply demand, especially in the remote areas, effort should be made to design pumping systems run by power available locally, such as solar energy, wind energy, bio gas etc.
In the developing world, renewable energies have been used, and are still being used for many centuries in the production and preservation of food, and the supply of water for human consumption and irrigation of crop etc. However, amongst potential new energy sources, solar energy, and especially the direct photovoltaic (PV) conservation of sunlight in to electricity, is extremely promising. Photovoltaic power has found application in all corners of Earth. PV technology is used in consumer electronics, refrigeration in the third world village pharmacies, utility scale projects, space applications, lighting and the water pumping. Amongst different terrestrial application of photovoltaic technology, PV water pumping is particularly important.
